Yes, it fits the plan and there are suggestions it will be available in 3.5
There is a 4 pack of them on offer too. 2 will apparently tow a Connie through Quantum. Bigger ships need more.

"Thus... I am torn as I skim through the ships page. Has anyone else felt the pangs of this conundrum? Am I worrying too much or expecting to do too much with the org?"
Look at my ship lineup We have both Exploration AND Industry. I have no combat ships of any measure lol
Why do you think you'll be of no use? I specifically designed my lineup to cover as much Industry as I could. I have also aimed at small crew ships. I did this because I dont want to push people for support and I like the freedom.
We have plenty of roles for all the ships currently on offer. You load your hanger how you want it and you play how you want to. There is always a place for people who want to be here

I think you are misunderstanding my issue I want to push the F key to switch engines on and off and spool etc. The Max is the only one in the range where that doesnt happen cleanly and simply from the cockpit seat
